Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from ibn Faddal from ibn Bukayr from Zurara from abu Ja’far (a.s.) who has said the following: “A believer is stronger than a mountain. A mountain loses its parts but no loss takes place in the religion of a believer.” وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (9/281))
